To all iff/1.0771, 'it iii/ty con/ecrit:

Be it known that L DLLoN Bennie, a citizen ot' the United States, residing' at Newark, in the county of Essex and State oi New Jersey, have invented certain new and useful improvements in Backing'Apparatus; and ldo hereby declaro the following to be a full, clear, and exact description oli' the invention, such will enable others skilled in tue art to which it appertains to' make and use the saine, Yz 'et'ei'ence being had to the accompanyinior drawings, and to characters of reference marked thereon, which 't'orin a part of this specification.

The objects ot' this invention are to secure in a racking' apparatus a more compact construction, whereby the machine can be einplojved in rooms where the ceiling' is low or the space otherwise restricted; to secure a construction which shall reduce the amount of material needed to build the machine, and, turthermore,conne the material to such kinds as are economical and commonly carried in stock; to cheapen the construction b v reducin g the labor involved; to secure an automatic action of the various parts of the racker as compared with manually-controlled parts; to secure an improved construction ot' pressureiiuid cylinders to cliect movements of the parts of the racker; to provide a main cylinder which shall be adjustable to any desired position; to positiveli,7 control the supply7 or liquid-flow in order to prevent leakage, and to obtain other advantages and results, some ot' which may be referred to hereinafter in connection with the description oi' the workinsoi` )arts v Theinvention consists in the improved racking` apparatus and in the arrangements and combinations oi'L parts ot' the saine, all substantially a. will be hereinafter set forth, and

ylinallv embraced in the clauses ot' the claim.

Ret'eri'ing'to the accompanying' drawings, in which like characters ot' reference indicate coi'- rcsponding' parts in each of the several iigui'es, Figure l shows in t'ront elevation a racking' apparatus ot' my improved construction. Fig'. 2 is a iront elevation of a single rackei'ariii, is a side elevation of the saine. t is a vertical sectional view of the upf per part oi a racking-arm; and Fig'. 5 is a Fig. Q shows in detail a certain guide-rod support. Fig. 10 is a side elevation ot the lower pai't ol the racking` .rm Vfrom the side opposite that shown in Fig. 2. l1.isacenti'al sectional view oi fl l'wer part of 'tho racking-arm with the ubc in position Jfor inliow ci liquid to a p. VFig'. l) is a crosssection, Upon line i,f, Fig'. 9., of a. certain valve employed for operating the c vlinders. Fig'. 13 is a vertical central section ot' a, falve employed Yoi' controlling, the iniiow andoutllow ot' gas and liquid from a package; and Figs. le, l5, and 1 are cross-sections of said valve, taken upon lines .2", .c and e, :'espectivelv, of Fig. 13.

ln said drawings, u. ./il. indicatesuitabie standards adapted te support tank 7), contaiiii the beer or other beverao'e to be racked int packages, said tank be provided with a pressure-gage c, sight-glass a, safety-valve d, and gas-charging connection Q' and being' entered at one end by a supplv-duct radine' 'from the liltei' through which the liquid is supplied. lo the front et' said standards fr. and tank /i are other standards, f f, siiitablj,r connected thereto and being' joined by a h i y, from which the individual lillingeariiis hereinafter described are suspended. i cylindrical chamber f2, is also supported upon the Vtraine of the apparatus, pi'e'liei'ablf,r by clamps l, fastening it to a parallel bai' or rod y', ci;- tending between the bars fl? connecting the standards (L a and ff. rthis chamber /i is 'l'or compressed air or gas, being; in communication, as by a duct l atene end, with a suitable source of supply and provided at seine point with a i'ii'essure-gag'e m.

The liquid-tardi chamber and supporting-bar ,f/ may be of auf.' desired length to accoinn'iodate any nuinbf-ii' n individual filling'- arms desired; out in inv application i have ing-tube and filling-head are both raised away from the package the center of gravity shifts and the device becomes top-heavy to an eX- tent sulhcient to cause its lower end to swing away from the package. YWhen drawn back again into line with the package, the rackingarm may be held by any suitable means, such as a hooked catch 48, engaging stops 49 on the arm.

For the inflow of liquid to my improved racking-arm a supply-pipe 50 communicates at the lower part of the inner cylinder with a passage 51 through the lower sleeve 17 and sheath 16 and adapted to register with the lateral opening 52 of the filling-tube tlowpassage 53. Preferably a check-valve 54 is arranged in said supply-duct, comprising a valve-disk 55, whose stem 56 has a pistonhead 57, working in a chamber 58 of a tubular branch 59 or' the check-valve. A spider 60 at the end of said branch 59 alfords aguide Vfor the val ve-stem 56., and between said spider and the piston-head 57 is arranged a spring 61, which with the flow-pressure normally holds the valve closed. A duct 62 opens into the side of said cheek-valve below the pistonhead 57 and through which pressure fluid is admitted, as hereinafter described, to open the check-valve.

The upper part of the sheath 16 for the filling-tube has a lateral opening 63, and when the filling-tube is elevated after the filling of a package its lateral opening 52 comes into coincidence with said opening 63 in the sheath, so that communication is established'with the space 64 in the lower part ot' the inner cylinder` This space communicates at its lower end, as by a passage 65, through the collar 17 and a lateral duet 66 with a valve to be hereinafter described, so that the lillingtube may be ven ted and its contents allowed to fall into the package. rlhis vent-opening 63 in the sheath, it will be noted, is, like the How-opening 51, between the upper and lower packings 19 43 of said sheath, and thus the lateral opening' 52 ot' the filling-tube has its limits of movement as the tube slides up and down between the said packings 19 43, so that it never crosses or engages them to cut or wear the packing material. In other words, the limits of movement of the lilling-tube render it absolutely impossible for the lateral opening to even reach the said packing's.

For controlling the inlet and outlet'of pressure liuid to the outer cylinder and inner cylinder `to move the inner cylinder and lillingtube, respectively, I employ valves 67 68, which are just alike and arranged upon the same pressure-Huid supply, so that a description of one will suffice for both. Each valve comprises a casing 69, (see Fig. 12 especially,) through the sides of which open ports 70 for the pressure-fluid supply 71 72, leadingy into the open air substantially opposite each other, 73, which communicates with the top of the cylinder, and 74, which communicates with the bottom of the cylinder. The rotary portion 75 of the valve is adapted to be turned by a handle 76 and has various transverse passages adapted to communicate with the ports described. One ot' said passages, as 77, extends diametrically of the valve, so as to connect the air-supply port 7 O with the opposite port 74, leading to the bottom oi the cylinder. At the same time this is done an angular sage 78 at one side of said passage 77 places the port 73 from the top of the cylinder in connection with the vent 71, so that the moving part in said cylinder will be Jforced upward.

To reverse the direction ot the pressure lluid, a branch 79 of the valve-passage 77 en- Iables the same when turned out of alincment with the ports 70 74 to connect the ports 70 73, a curved passage 8O on the opposite side ot' the middle passage 77 from the first-meutioned passage 78 then connecting the port 74 for the bottom ot the cylinder with the second vent-port 72, as shown in Fig. 12. rQhus by a slight rotary movement of the valve-plug 75 the direction of the ,ressure fluid to the cylinder may be varied at will to drive the moving' part in said cylinder in either direction.

The valve 67 for the main cylinder 1 is connected by pipes 81 82 with the top and bottom of said cylinder, respectively, and thus supported, a flexible tube 83, leading from` the main air-supply pipe 84, permitting relative movement of the two cylinders. The lower valve 68, or one for the inner cylinder 7, is supported thereon by means of tubes 85 86, leading to the top and bottom ot' said lower inner cylinder. respectively. A branch pipe 87 leads to said valve from the main pressuresupply pipe 84, and said supply-pipe 84 is flexible to permit movement of the cylinder.

For controlling' the flow of gas in charging' and venting the packages and also tor controlling the check-valve 54 in the liow-pipe 50 I employ a valve 88, which is located at the side of the lower part ol: the inner cylinder adjacent to the packing-head. Said valve 88 comprises a casing 89, in which a plug or valve proper, 90, lits imperviously, having' a handle 91 at its upper end outside the casing for turning, a spiral spring' 92 being arranged between the top of the casing and the top ot' the valve proper, all as is common in valves. Said valve proper and its casing have passages and ports on three planes, one above the other, as shown all together in Fig. 13 and separately in Figs.' 14, 15, and 16. 1n the upper plane a port 93 in the casing is connected, as by a pipe 94, with the com pressed-air or gas supply, and the valve-plug has a Y-shaped transverse passage, the stem 95 of which is adapted to be turned inteI coincidence with the said airsupply passage 93. Wlhen this is done, one

of the branches, as 96, of said Y-shaped passage communicates through a port 97 in the IOO IIO

Igo

vi'Llvc-casing with the duct/17, before referred to, which con'ununicates through the packing-head with the package to be lilled. (filas can therefore pass freely into the said package to charge the same. Upon throwingl the valve-lever to its opposite limit, as hereinafter more 'fully described in connection with the simultaneous operation ol? the three series of passages oll the valves, the stem 95 of the Y-shaiied passage coincides with a ventopening 98 in communication with the gaspressure above the liquid-supply, hereina'litermore fully described, its other branch arm 09 now registering with the passage 97, leading to the package, so that gas may escape therefrom as the liquid enters.

At its lowest plane, or the one at line e in Fig. 13, the valve-casing has a vent-port 100, an air-inlet 101, connected, as by a pipe 102, with the compressed air or gas supply 103, and a port 10a, connected by the duct 62 with the check-xf'alve ,fi-tin the snpi'ily-pipe. The .said vent 100 and the port 104, leading to the check-valve, are adapted to be in communication when the valve is in position shown in Figs. 13 and 16 by a passage 105, so that compressed air or gas beneath the head 57 ot' the check -valve piston is vented and said valve permitted to close. lt will be noted from a comparison ol Figs. 1-1- and 10 that this connection is made when the ports at the top plane of the valve are all closed or the valve-plug at the intermediate position to which it is thrown as soon as the package is iull. The upper part oi the valve thus cuts oli' the veut from the package to prevent liquid rising thereinto. and simultaneously the lower part of the valve closes the checkvalve 5a to stop further inliow Vfrom the liquid-supply. `When, however, the valve-plug 90 is turned in position to have the passages 90 05 in its upper part connect ports 97 and 98 tor venting of' a package, a branch 100 of the passage 105 at the lower end oil the valve registers with the checlmfalve port 104, while one end ol said passage 105 registers with the air-inlet 101 and the other end is dead. This admits pressure beneath the check-valve piston 57 to open said check-valve, and iilling and venting ot' the package begin simultaneously.

@n its middle plane, or at line 22, Fig. 13, the valvc-i'ilug 00 has a single transverse passage 107, adapted to coincide at its opposite ends with a vent-port 108 and a port 10), opening into the pipe 66, leading froml the chamber 64C ot the inner cylinder 7 and adapted, as above described, to ventthelilling-tube. Thus when the valve-plug is brought into the position shown in 1-1 to shut oil both 'llow into and venting from the package communication will be established by the passage 107Y between the open air and said chamber G-t, so that as the filling-tube is raised it will be vented at the top and its contents allowed to pass into the package. 'in other positions of the valve-plug this passage 10T is dead at both ends.

1n the operation of my improved racking device an empty package is brought beneath one ot' the arms, it being understood that the liquid-tank is constantly being supplied under uniform pressure and that above the liquid therein a predetermined pressure ot', say, ten or twelve pounds has been introduced through valved inlet q and then cutoli. The cylinder /L is in constant communication with the gas-supply means wholly independent of the above-mentioned gas-pressure above the liquid in the supply-tank. The vent-openingl 98 of the valve 88 is also in communication, as by a iiexible tube 108, having a sight-glass 100, with the top oi the liquid-supply tank 7). The air-supply tube 103 to the said valve 88 is connected to the gas-chamber 71 and likewise the pipe `8a, which suppliesair to the cylinder-operating valves 57 and 68. Said chamber /z/ carries a pressure ot, say, titty pounds,and,as stated,is continuously supplied. A package being' in place, the valve 8T, controlling the pressure-fluid supply to the outer cylinder, is then turned to admit pressure fluid to thel upper part of said cylinder and torce the inner cylinder down until its packing-head 24. is in impervious engagement with the package, when the f'alve 67 is turned to an intermediate position,where all its ports are closed, or may be left with pressure alive to prevent relaxation from leakage or the like. The valve 08 is then manipulated in a manner precisely similar to that just described ot' valve 07, and as a result thereof the l'illing-tube is projected into the package.

To facilitate making connection with a package, as just described, the length et the lilling-tube is such that its lower end is never entirely withdrawn up into the inner cylinder, but projects to enter the bung-hole ahead ot' the engagement of the packing-head with the package, and thus serve as a guide to center the filling-arm with respect tothe package. This downward movement o' the lilling-tube brings its lateral opening 52 into coincidence with the liquid-supply passage 51. y1`he checkvalve 51 in the supply-duct is closed, it will be remembered, and the valve 88 is .standing with its three planes or series of passages as shown in Figs. 14C, 15, and 16, respectively-w that is, the upper one is dead, the lower one venting the check-valve 54.- to allow it to stand closed, and the middle one open to the chamber 641 of the inner cylinder, but which chamber is at this time idle. The plug 90 of said valve 88 is now turned in the direction ot' the single arrow shown on Fig. 1%, which brings the passage 95 oi' the upper series into registration with the air -inlet 9a and the branch passage 9G into registration with the port 97, leading to the package. The other branch, 99, is dead, as are also the passages of the lower and middle series of the valve, so that the oniy effect is that the package is given a primary charge from the gas-chamber /"t. This occupies but an instant ot time, and then the valve-plug1 9() is swung` to the other limit of its range of oscillation, as shown by the double arrows in Fig. l-l. This brings the passages 99 ot the upper series or plane et' said plug into registration with the ports 9S 97, respectively, and opens up communication between the package and top of the supply tank to permit venting, the other branch, 96, being dead, as is also the passage 107 of the middle series. @f the lower series or plane the passages and 10-5 connect the air-inlet 101 with the port 10s, leading' to the checkvalve 54:. so that pressure is admitted beneath the piston ot' said check-valve to open the same. Flow into the package now takes place by gravity, the primary gas-pressure therein escaping,l to the top of the liquid-supply tank to take the place oi the liquid, and it "here is a surplus it is relieved by the safety-valve (I. lhen the package is vtull and liquid appears at the sight-glass 109, the plugi Q0 ot' the valve S8 is swung' or turned back to its original position midway ot' the ends oi' its range of movement. as shown in Figs. 1B, lei, 15, and 16. This closes the check-valve 5-l to stop the iiow o' liquid, stops venting` Jfrom the package, and opens up the vent 108 to the chamber (Si ot' the inner cylinder. The valve (58 is then operated to admit pressure to the vbottom ol the inner-cylinder chamber 13 and exhaust from its top, thus driving i the piston-head upward and carrying the tilliug-tube out of the package. This upward movement ot' the lilling-tube first carries lateral openingZ out of coincidence with the How-opening 5i, through which it has been receiving liquid, and this, in addition to the f then operated to admit pressure to the bottom ot' the outer cylinder and exhaust from its top, thus d riving its head 21 upward anddiseneaging' the packing-head AFrom the package. rl.`he package is then banged and removed.

Yit will be understood that the body ot' gas in the top ot' the supply-tank is after its introduction positively cut oli from its supply source by a cock in the connection q, so that it is actually a detached body. Furthermore, ,l would point out that the stops 0 p in the inner cylinder positively limit the movement oi' the lilling-tuhe, so that the lateral opening 52 cannot pass beyond the packings 1.9 t3 ot' the sheath 16, and obviously Huid-pressure Yfor n operating the cylinders oi my improved lillintr-arm may be compressed gas (preferably air) taken from the chamber t, as shown, or

may he any other suitable fluid supplied in any ordinary and well-knowi'i manner.
